Glass Fibre hydrolysis aging
Fenómeno do problema
Glass Fibre product in humid-hot environment mechanical properties drop >25%
Análise das causas
Glass Fibre contains polar groups, hydrolytic chain scission under humid-hot conditions; ester bonds/amide bonds etc. sensitive to water
Solução
1) Select low-polarity-content grade to reduce hydrolysis tendency; 2) add anti-hydrolysis stabilizer; 3) coat product surface with waterproof layer
Conclusão principal
Hydrolysis aging is caused by polar groups' sensitivity to water; selecting low-polarity grade is key
